The combination of oil with high refractive index and oil with low volume expansion: The mechanism for the high transparency and low sweating effect of the oil is not always clear, but it is not susceptible to the temperature of oil with low volume expansion It is speculated that the nature is related to low sweating.
The present invention can produce a clear, oil-based solid cosmetic having high storage stability that exhibits the desired effect as long as the required amount of the oil agent is contained as an oily solid cosmetic.

  In particular, by selecting and using the oil agent having a refractive index of 1.460 or more at 20 ° C. and the oil agent having a volume expansion coefficient of 0.065 or less according to the present invention, high transparency and low sweating property can be obtained. Provide quality cosmetics. Needless to say, a single oil may be used as long as it satisfies the conditions of the refractive index and the volume expansion coefficient simultaneously.

Hereinafter, the present invention will be described in detail based on preferred embodiments of the present invention.
The transparent oily solid cosmetic composition of the present invention is a cosmetic composition used for body, face, hair and the like.

In the present invention, the “solid cosmetic” is a cosmetic which can maintain its solid form at normal temperature (25 ° C.).
In the present invention, "cosmetics" is a material that can be used to manufacture, but not limited to, body care products, skin care products, makeup products, hair care products, fragrance products and the like.
